LASTING-MACI-IINE SPEED-CONTROLLING MECHANISM.

To all wiz-m t may concern Be it known that I, MATTHIAS BROCK, a citizenof the United States, residing at .we Boston, in t-he county of Suffolkand State of Massachusetts, have invented certain Improvements inLasting-Machine Speed-Controlling Mechanism, of which the followingdescription, in connection with the accompanying drawings, is aspecification, like refcal driving mechanism is caused to actuateoperating tools at one or another speed according to the position towhich a treadle is depressed. In the use of this particular lastingmachine the operator'h'olds the shoe in his 1 f'. hands for the actionof the gripper and tack driver upon it and this presentation of the shoerequires skill and involves substantial physical eiiort when continuedthroughout a days work. It is therefore important to make s: otherconditions as easy as possible for the One of the desirable conditionsoperator. is freedom to stand squarely and firmly upon both feet. Ithasbeen found in practice that a substantial degree of fatigue resultsfrom the use of the invention of said patent andil the practical valueof that invention is substantially reduced by reason of the fact thatwhile using one of the speeds provided for, the operator must stand onthe heel only of one foot to maintain the treadle in a mid position.

It is the specific object of this invention to overcome this difficultyby providing a'- rm and complete rest for the o perators treadlecontrolling foot in all positions of the treadle.

More broadly, it is an object of this invention to improve speedgoverning mechanism generally wherever the invention can be applied.

The several features of the invention willl be explained in connectionwith the accom@ panying drawings showing a plurality of embodimentsthereof and then the generic invention, together with one speciesthereof Specification of Letters Patent.

Figure 1 is a side elevation of the lower "1' portion of a lastingmachine of the hand method type such as shown in said patent andequipped with the variable speed mechanism which forms thesubject-matter of that patent, together with a treadle stop Il' made inaccordance with this invention Fig. 2 is a side elevation showing apre`J ferred embodiment of this invention; Figs. 3 and 4 are perspectiveviews showing inoperative` and operative positions respectively 'f'l ofthe treadle stop shown in Fig. 2; Fig'. 5 shows a third embodimentof theinvention comprising a treadle with two foot plates arranged atdifferent distances from the floor; Fig. 6 is'a perspective view of thesi treadle controller shown in Fig. 1 and gov- -erned by the knee of theoperator; Fig. '7 is a diagrammatic view indicating the lateraldisplacement of the speed controller effected lby partial and by fulldepressions of the treadle.

The shaft 2 having the fast pulley 4l turned continuously by belt 5 andhaving, the fast clutch element 6 is the driver and voperates throughloose pulleys 8 and 10 which alternatively coperate with the fast clutchelement 6, to actuate the large or the small pulleys 12 and 14 forturning shaft 15: to operatethe gripper and the tacker of the The clutchelement 6 normally occupies the central relation to pulleys 8 and l()which is shown in Fig. 1V

and this position is maintained by forceA transmitted through the lever16 pivoted on the link 17, through the treadle rod 18 and the treadle 20from the spring 22 that eX-' tends from the treadle to the frame andholds the treadle uplift-ed. These parts are or maybe all as describedin said patent.

In the form Shown in Figs. 1 and 6 a treadle stop 25, comprising a hookto eX- tend under and into supporting engagement with the treadle footplate, is adjust-ably at, tached to a lever '26 pivot-ally connectedwith the machine column at 27 and having its up per end in the path of asecond lever 28 that extends into the knee fork 30 in which the operatorrest-s the knee of the leg by which he stands on the treadle 20. Inwardpres-l `sure by the knee swings the stop 25 under the treedle 2O fromwhich position it is Withdrawn by spring 32 when pressure is relieved.

In the construction shown in Figs. 2, 3 and l a treadle stop 35 ispivoted between ears 36 on one lateral side of the treadle footplate andis held by a spring 38 in the position shown in Fig. 3 and in full linesin Fig. 2.
